Alexandre Garnier commented on LBCORE-213:
------------------------------------------

Multiple <to> elements is a good idea for clearness in configuration file when settings the email addresses in it.
But restrict to only one email address by <to> and silently ignoring surplus addresses is just too restrictive.

> It's not possible to have multiple email address in <to> element of SMTPAppender because only the first one is used (https://github.com/ceki/logback/blob/master/logback-core/src/main/java/ch/qos/logback/core/net/SMTPAppenderBase.java#L270)
> When using a property, multiple <to> element is not really easy (if even possible)...
> Example:
> <appender name="email" class="ch.qos.logback.classic.net.SMTPAppender">
>    ...
>    <to>${mail.log.to}</to>
>    ...
> </appender>
> With properties :
> mail.log.to = admin at domain.com,dev at domain.com,op at domain.com
> => Only admin at domain.com get the email !
